Abstract
In a non-clutch compressor, by controlling a differential pressure between a crank chamber accommodating an oscillating plate therein and a cylinder chamber in a suction stroke, an incline angle of the oscillating plate is sequentially changed so that a maximum stroke of a piston is changeable. The compressor includes a passage opening and closing device arranged at an inlet section of one of a suction pipe connecting with a suction chamber of the compressor and the suction chamber, and a pressure control valve arranged between a discharge chamber and the crank chamber, the valve opening in a case where pressure in the suction chamber is less than a set value. In the compressor, a cross-sectional area (A) of a passage of a discharge hole for connecting the crank chamber with the suction chamber is expressed by an equation: 0.5<(A)<1.8 mm.sup.2.
